The present invention relates to an improved machine for handling bread and cake dough, especially adapted for dividing the doughvand extruding it in varying sizes of deposits, for making rolls, biscuits, Vdough'- nuts and the like.

The inventionhas-orits purpose to provide a machine of this character, wherein the dough may be i'ed into a hopper, divided intoA requisite quantities, and then extruded through passage, and iinally into biscuit, roll or Vdoughnut `forming chambers of a rotating head, and from which such deposits of dough are vautomatically discharged,the

' mechanism for dividing the dough'and rotating the head having the biscuit or roll yforming chambers, including means for operat ing them synchronously and coordinately.

However, the head with the dough receiving chambers for forming rolls or biscuits receives an intermittent motion co-ordinately with the d Tiding feed of the dough.

Another purpose is to provide, in a-machine ci this kind, a mechanism for intermittently V,detaining the head with the dough .receiving chambers, whereby` each chamber may be registered with the outlet oi the dough extruding passage, so thatthe req-v uisite amount of dough may be extruded into the chamber, in conjunction with means for permitting a clutch to take hold and impart rcvoluble movement to a gear on a shaft which 'carries the rotating head having'the chambers, allowing the head to be moved to bring another chamber in register with the dough extruding passage, there being means for discngaging the clutch, allowing the head to remain with its chamber in register with said g the mechanism being so arranged that the mit the machine to repeat these operations.

Another purpose is to providemeans `for gauging the amount of vdough to enter the chambers as they intermittently regi-ster with the extruding passage, there being a graduating scale for indicating the amount of dough entering Athe chamber.

A further purpose is to provide discharging means in the chambers for discharging Figure 3- is a sectional passage, until the next chamber is filled,

the dough deposits, said discharging means yto be setto gauge tlie'size of the deposits, so

Vas to produce varying sizes of biscuits, rolls, doughnuts andthe like. 1

'A still'further purpose is to provide an improved dough dividing and eXtruding'ieed tocontinuousy rotate and including intersecting dough dividing blades which are carried byv a rotor operable 'in the main dough receiving chamber, saidblades having anexti'uding feed actionat the "same timethe dough is divided, so as to feed the dough y through theV passage in order thatit may be extrudedV into tliedough receiving chambers of the head, said casing having guidesfor the intersecting blades, so as to retain them in their proper positions.

lt is to be understoodthat the particulars herein given are in Vno wayli1nitive,'and that whileV still keeping within the scope of the invention, any desired modification oi details and proportions may be made'in the construction `of the device according to circumstances.

Referring to the drawings-1 identifies a' base, and mounted upon the base is a frame 2, which includes the legs43., One end ofthe frame has a boss v4,1which and a part of the frame 2 at its end constitutes a bearing having a shaft 5, the-lower end of'which has a bearing in the base 1 and carries a spur gear 6. 1The upper end of the shaft has secured thereto an lintermittently revoluble head 7 `which Vhas a plurality of dough lreceiving chambers 8. The'chambers are radially arranged' and operable therein areplungers 9, which have stems 10 guided inthe bottom wallsof the vchambers 8 as identified at 11.

The stems 1.0 have longitudinal grooves 12,V

shown in dotted lines in Figure 3,there being set screws or pins 13 extending transversely7 lindrical casing 24, the interior of the casing communicating witha passage formed in the castiifg 21. .Y The passage 25 in the casting'21 also registers with an opening in the lwall 19', and where this register takes place an arcuate plate 26 is Yceui'itersunk .in the curved4 farce ofthe wall .19, and with which the cylindrical face of the head 7 engages.

' Tlie'pl'ate 26 has an opening 27, which regfisters withltheseveral chambers of the .head 7, and one-edge of the opening. 27 of the plate is extended toward the centre of the opening 27 and sharpened, acting to shear the of the bottom walls of said chambers with their extremities engaged within the grooves 12 to guide and retain the stems against rotary displacement.` The stems 10 are radially positioned relative to the head 7, and as shown in Figure 8 the under part of the plungers 9 are disposed adjacent the bottom walls of thechambers 8, the stems are positioned or extended into the chambered out part of the head.-

The boss 4 has secured vthereto by means of welding or a pin or the like as at 14, a cam tongue 15, to be engaged by the ends of the stems 10, to actuate them and force the plungers outwardly of the chambers 8 for the purpose of discharging the dough deposits, according to the size of biscuits, rolls or doughnutsas. may be desired. f

This head 7 comprises a body 16 and opposite plates 17, the latter being secured to the body 16 by means of bolts 18 asshown clearly inFigures 2 and 3. Y

Mounted upon the frame 2 in any approved manner vis an'upstanding `wall 19,

which has an arcuate face 20 concentric with the head 7, and in which the cylindrical surface of the head engages, as the latter rotates intermittently. v ,A

A casting 21 is` secured to the upstanding i wall 19 Vby means of angle plates 22, which are secured by screws or the like 23 to the casting, and thewall, as shown in Figures 1, l2 Aand'3. This casting 21.1nerges into ka cyhead7 is chambered out, so -thatwhen the sions 34 receive the opposite facesv of A dough od after itentlers the roll or biscuit forming chamber, said extended and sharpen ed portion of the edge `of the opening being designatedby the numeral 26, as in Figure 3.

Eccentrically in the casing 24 is a cylindrical body member 29`provided with intersecting radial slots 30, in which'are guided intersecting dough dividing and feedingv blades 31,'which not only act to divide the dough but alsoV feed and. causefan eXtruding action to take place. In order that the blades may intersect, their central portions are cut away as shownin Figure 12, said cutawayportion of one blade straddling thecorresp'onding portion ofthe other blade and vice versa.

, As previously stated the blades 31 are cut away to permit them to intersect each other, y

and are mountedin the radial slots ofthe cylindrical body member 29. This body member is eccentrically mounted in the casing .24, and theposition it assumes necessitates the casing 24to be swelled at a portion thereof identified by thel reference character 24a, in order ,to permit the blades 31'to reciprocate across the diameter of the cylindrical body member 29. When each blade'31 assumes a position, which is assumed bygone of the bladesin Figure 8 extending on an 1ncline toward the left, it is necessary that the wall of the casing 24 must be swelled at the point 24a, in order to permit the blade to move with the cylindrical body member 29. Unless such a swell is provided, the blades, during their actions would jam or bind, and thereby render the machine inoperative. A plate is secured by screws 32 `to the cylindrical body member 29, for the purpose of retaining the blades in the slots. lThe casing 24 has opposite head plates 33, which have circular depressions 34, which are arranged eccentrically of the casing 24. The depreflst e cylindrical body member 29, which is capabley of revoluble movement, due to the fact ythat .one face of the body member '29 has an a sprocket 37, with whichY a sprocket chain.

38l engages. The casing24is` provided withy a'. suitable hopper 39 into which 'the' doughV to beni-vided andextruded is fed.;:.As ithe dough enters the hopper 39 it is picked up by the' bla-des 31, the blades acting todivide the dough in 45, with which a worm 46 meshes, the latter being carried by aV shaft'47, which may re,- ceive power from any Ysuitable source `not shown, preferably a motor;

The other end of the shaft 44 carries abeveled gear 48 which meshes withk a-rsmaller gear 49 onta shaft 50, which ismounted in a bearing of the. base l. The upper end of the shaft 50 is mounted in a bearing of a plate 52 secured to the under'face ofthe frame Q. "lheshait 50 carries a gear 53 which meshes with the'spur gear 6, and on Vthe, lower part of the shaft 50 is arectangular collar 54, with `which. a leaf spring 55 engages. The :faces of this rectangular collarq54 are posi'- tioned coincidentto thechambers S, so that when the shaft 50 is rotated the spring 55 will engage with one of the faces and'retain the head 7 with one of its chambers S in register with vthe opening 27 of the plate Q6, so that the dough may easily feed intoA the chamber registering with said passage.

Vlhe beveled gear `49 is loose upon the shaft 50, and is provided with a, plurality ot small cavities or depressions 56. A suitable sleeve 5T is keyed to theshaft 50-l as shown in Fig* ure 6, and the upper end of the sleeve is reduced as identilied at 58, therebyV causing the shoulder 59 to be formed. rlhis sleeve has a longitudinal verticallyarranged slot 60, which is counter-slotted as at v671; Mounted in the slot 60 is al clutch strip 62, with a lug 63 on its lower end, and which is designed to enter i-n one ofthe depressions or cavities 56 of the loosely mounted gear 49, so as to pick up the gear and cause it to rotate in the direction of the arrow a in-Figure 4. A. cover plate 64 is secured in thecou'nterf slot Glby meansof screws 65, to retain the clutch strip 62 in the slot 60. The upper end ot' the 'clutch strip has a lateral lug 66 and is provided with a cylindrical here 6'7, which receives a downwardly projecting guide pin 68 depending from the collar 69 ofthe sleeve 57, there being a spring 7() between the lower end of the depending pin 68 and the bottom of the bore, thereby acting to force the clutch strip downwardly in the direction olf the loose gear 49.

Depending from the frame 2 and secured therein in anyapproved .mannerisa stud 71 carrying :leven 72 which has-a team .173/.at onefe'nd.;v The carinv .carrying end of the lever 7 2 .rides upon the'should-er 59fofithe sleeve'57 j ust in thepathy of thelateral lug 66,1"so-that when' the sleeve 57 i rotates .in the direction ofthe arrow la, the ylug, may vrideu-p ,upon

' the. cam 73 atythe same. timefthe spring 5 5 engages lone o-'the flat placesv offthe rectangulai'collar 54 on the shaft 50, until the clutch strip 64 Aagain picks up the' loosev .gear 49 au d imparts@ further movement.: thereto;

'l he stud 7l is rotatable in the frame 2, and

its upper end carries ,at 71er a lever 74, which is under tensionof a spring 75, to retain the cam end ofthe lever 7 2 against the side of the sleeve 57.Y The lever 74 hasa sectorf76 ait its outer end, and upon the upper face of which' a. graduated scale 77 Vis provided.

Pivoted at 78 on thelever 74 ips-a gauge member 79 having at its inner end an upstanding lug 80, and its outer end 'carrying a bolt 81, which extends through a slot 82 in the lever 74, the head of the-bolt engaging beneath the lever 74, while threaded to its. shank4 is a thumb `nut 83; y u f lhe upstanding lug S0 is positioned :adjacent the shalt 5 at'its upper end just in the path of the stemshlo the plungers 9,l

acting to limit the stems in their movement radially or" the head 7. It is possibleto release the thumb nut 83 and set the gauge member 7 9, and again tighten the thumb nut 88, so as to `position the upstanding lug-80 at`clilfeifent'locations, for limiting the inward lateral movement of `the Sterns, and thereby govern thepositions of the plungers 9.

l7l7hen the dough enters thechamber '8, it pushes thel plunger 9 inwardly, until the stem is limited in its inward movement, the plunger likewise being limited, so vthat only a certain quantity of dough may enter the chamber 8 lVhen the lug 80 is positioned substantially close to the. shaft 5, it is possible for the stems l0 `to move to their limit radially Vinwardly, and; in whichV case the plungers 9 are engaged with the bottoms ot the chambers 8. i In the operation .the gauge member 79 is iositioned toffauoe the amount of dough l to b t) to* enter the chamberdand then the lever 74 ismoved, and thereby moving the lever 7 2, disengaging the cam 73 from under the lateral lug 66', allowing the lclutch strip to move downwardly until its lug G3 engages one ot' the depressions 56.

lAs soon as the lug engages a depression 56, the loosely mounted gear 49 is picked up and rotated with the shalt 50, and since the shaft hasa gear 53 meshing with thelspur *gear 6, the head 7 rotates, until a chamberS'is filled with dough, and its diametri'cally opposite chamber has discharged adough deposit, through the medium of the-stem vof a plunger 9 engaging with al cam tongue l5. Theshaft 50 makesfa 'complete revolution, until the lateraln lug 66returns toa position engaged upon thertopofthe cam 713. These operationsV arevrconsecutively repeated,jit .being understood that the-lever74 isvto be manipulated'to release the clutch strip from its raised position; 'As previously stated, the

Y shaft Lil carries power to -the shaft 35 and the rotorf29, soas to ,cause movement'to be imparted tofthe blades, which will act to Y plurality of dough receiving chambers, pis,-
